Turning off water supply to shower

Anonymous user 15/03/2024 - 2.32 PM

Hi, I would appreciate some help! I am trying to isolate the (cold) water supply to an electric shower in the bathroom. I think the shower is fed from the same supply pipe as the bathroom cold water taps. I have gone into the attIc and closed the gate valve labelled “cold water feed” on the outlet from the cold water storage tank. I have the opened the bath and basin cold water taps to draw off as much cold water as possible from the pipe. But here’s the problem. The cold water keeps on flowing from the taps, whilst the level in the cold water storage tank in the attic decreases and the mains supply ball valve opens to let more water into the tank. Any suggestions? Have I missed something blindingly obvious? Thanks in advance. Andy.
